How to deploy the war package to docker
The method of placing the war package into tomcat under docker is as follows:
1. First, you need to put the war package into the centos system. In this article, a test.war project is placed into the main directory of the centos system. This can be placed into centos through the ssh tool. Everyone should be familiar with it. Familiar, the format is as follows:
scp local_file remote_username@remote_ip:remote_folder
2. Move test.war from centos to the container started by the tomcat image under docker.
(Related video tutorial sharing: java video tutorial)
docker cp test.war containerID:/usr/local/tomcat/webapps/
Description:
containerID is the container ID or container name of the tomcat image you started That's ok too.
This is to put test.war under tomcat's webapps
Common docker commands
For the convenience of understanding, here we take the tomcat image as an example . One line of syntax description and one line of examples.
Generate a container through the image
docker run -p port1:port2 containerName:tag docker run -p 8080:8080 tomcat:latest
Start an existing container
docker start containerID/containerName docker start admiring_turing
Among them, admiring_turing is the name of a container created by the tomcat image, and its container ID can also be used
Stop a container
docker stop containerID/containerName docker stop admiring_turing
Restart a container
docker restart containerID/containerName docker restart admiring_turing
Interactively operate with a started container
docker exec -i -t containnerID/containerName /bin/bash docker exec -i -t admiring_turing /bin/bash
Copy files to the container
docker cp src_path container:dest_path docker cp /test.txt admiring_turing:/usr/local/
test.txt is a test file created by myself and copied to the /usr/local directory of the container.
Running a container in the background
docker run -d -p image:tag docker run -d -p tomcat:latest

Select Docker in a small project or development environment, and Kubernetes in a large project or production environment. 1.Docker is suitable for rapid iteration and testing, 2. Kubernetes provides powerful container orchestration capabilities, suitable for managing and expanding large applications.

Docker is important on Linux because Linux is its native platform that provides rich tools and community support. 1. Install Docker: Use sudoapt-getupdate and sudoapt-getinstalldocker-cedocker-ce-clicotainerd.io. 2. Create and manage containers: Use dockerrun commands, such as dockerrun-d--namemynginx-p80:80nginx. 3. Write Dockerfile: Optimize the image size and use multi-stage construction. 4. Optimization and debugging: Use dockerlogs and dockerex

Docker is a containerization tool, and Kubernetes is a container orchestration tool. 1. Docker packages applications and their dependencies into containers that can run in any Docker-enabled environment. 2. Kubernetes manages these containers, implementing automated deployment, scaling and management, and making applications run efficiently.

The purpose of Docker is to simplify application deployment and ensure that applications run consistently in different environments through containerization technology. 1) Docker solves the environmental differences problem by packaging applications and dependencies into containers. 2) Create images using Dockerfile to ensure that the application runs consistently anywhere. 3) Docker's working principle is based on images and containers, and uses the namespace and control groups of the Linux kernel to achieve isolation and resource management. 4) The basic usage includes pulling and running images from DockerHub, and the advanced usage involves managing multi-container applications using DockerCompose. 5) Common errors such as image building failure and container failure to start, you can debug through logs and network configuration. 6) Performance optimization construction

The methods of installing and using Docker on Ubuntu, CentOS, and Debian are different. 1) Ubuntu: Use the apt package manager, the command is sudoapt-getupdate&&sudoapt-getinstalldocker.io. 2) CentOS: Use the yum package manager and you need to add the Docker repository. The command is sudoyumininstall-yyum-utils&&sudoyum-config-manager--add-repohttps://download.docker.com/lin

Using Docker on Linux can improve development efficiency and simplify application deployment. 1) Pull Ubuntu image: dockerpullubuntu. 2) Run Ubuntu container: dockerrun-itubuntu/bin/bash. 3) Create Dockerfile containing nginx: FROMubuntu;RUNapt-getupdate&&apt-getinstall-ynginx;EXPOSE80. 4) Build the image: dockerbuild-tmy-nginx. 5) Run container: dockerrun-d-p8080:80

Docker simplifies application deployment and management on Linux. 1) Docker is a containerized platform that packages applications and their dependencies into lightweight and portable containers. 2) On Linux, Docker uses cgroups and namespaces to implement container isolation and resource management. 3) Basic usages include pulling images and running containers. Advanced usages such as DockerCompose can define multi-container applications. 4) Debug commonly used dockerlogs and dockerexec commands. 5) Performance optimization can reduce the image size through multi-stage construction, and keeping the Dockerfile simple is the best practice.

Docker is a Linux container technology-based tool used to package, distribute and run applications to improve application portability and scalability. 1) Dockerbuild and dockerrun commands can be used to build and run Docker containers. 2) DockerCompose is used to define and run multi-container Docker applications to simplify microservice management. 3) Using multi-stage construction can optimize the image size and improve the application startup speed. 4) Viewing container logs is an effective way to debug container problems.
